Abstract

A theoretical study of time dependence in CoCr thin films is presented. The study involved using a Monte Carlo model and taking into account the magnetostatic interaction between the columns. Logarithmic time dependence was observed as a result of the dispersion of local interaction fields. The statistical behavior of small areas of the film was studied and shows good agreement with experiment. Similarly good agreement is found for the temperature variation of the viscosity coefficient and remanent magnetization
